Questions
How big is the Triplefive PCB?
It measures 29 × 29 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Triplefive use?
8 parts, built around the NE555P. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Triplefive KiCad files?
From the iamjo-maker/pcb-designs repository on GitHub, at the commit this page was made from: the board is 555Blinker/triplefive.kicad_pcb and its schematic 555Blinker/triplefive.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Triplefive design in my own project?
Its repository states no licence, so its author keeps all rights: ask iamjo-maker before reusing the design.
